24. The monolayers were self-assembled from 20% hexadecane solutions. HMDE was rinsed with ethanol and transferred to a 0.5 M KCl solution. We observed no systematic differences in the results of the subsequent capacitance measurements regardless of the duration of the self-assembly seep in the range from 5 s to 10 min.
25. c = vC. Polarization of monolayer-coated HMDE's beyond -0.9 V vs SCE results in their desorption.
26. The film thickness was calculated using the known bond lengths and angles. In addition, 1.0 Å was taken as a van der Waals radius of the terminal methyl groups. An all-trans conformation and the perpendicular orientation of the alkyl chains with respect to the electrode surface were assumed.

28. 2 (the average and SD of 20 determinations made by weighing 10 drops of mercury). The drop expansion experiments were earned out in small increments each increasing the electrode surface area by ca. 7% of its initial value.
